Enterococci are bacteria that are found in the GI tract of warm-blooded animals, which includes all birds and mammals.  Their presence in surface water indicates recent contamination with fecal waste.  Counts are expressed as cfu or colony-forming units.  Counts greater than 104/100 ml are shown in red as they indicate that water is not suitable for recreational use. 

 

Values greater than 104 are shown in red as they are considered unsafe for swimming or recreational use.
